Hi, John!
What have you been up to?
I haven't written for so long, but I had been very busy during these weeks.
You don't believe what happened last, we have won a prize of Champions' League among schools in our town. Unfortunately I've got some bad news. I've damaged my leg and will not be able to play football at least for two months. I hope everything will be O.K. You don't have to worry for me.
I'm looking forward to hearing from you.
Say hello to everyone who remembers me.
Waiting for your letter.
Best wishes .
Hope to see you soon.
Tom.
